Practical to reduce engine/ compression braking?

I'm wondering if there is a practical way to reduce engine braking?

The issue: I find that in autocross situations in 2nd gear engine braking is much more significant than at the track. In these situations the extra braking at the rear while turning in often causes the rear to begin to rotate more than ideal, slowing corner entry. Not unexpected with a high compression 3.6 spinning at 7500 rpm...

Of course normally this is dealt with using driving style, suspension, alignment and brake bias, but it occurred to me that reducing engine braking itself would be useful. I'm not sure there is a practical way to do that, however? I can imagine increasing the air past the throttle plate might have a small effect (increasing idle)? I'm not sure that would be noticeable, and I can't think of much else... I'm thinking specifically about 3.6 VRams and GT3 motors, but also in general.

Any ideas?
